Ruby on rails '；作为可注释的，带有线程'；不保存评论,ruby-on-rails,ruby-on-rails-3,acts-as-commentable,Ruby On Rails,Ruby On Rails 3,Acts As Commentable,这是我的表格： <%=form_for [current_user, @tattoo, @comment], :remote => false, :html =>{:multipart => true} do |f|%> <ol> <li> <%=f.hidden_field :commentable_id, :value=> @tattoo.id %><br <%=f.lab

这是我的表格：

<%=form_for [current_user, @tattoo, @comment], :remote => false, :html =>{:multipart => true} do |f|%>
  <ol>
    <li>
      <%=f.hidden_field :commentable_id, :value=> @tattoo.id %><br
      <%=f.label :body%>
      <%=f.text_area :body, :style=>"width:320;height:80px"%>
    </li>
    <li class="submit">
     <%=f.submit "Add comment"%>
    </li>
  </ol>

<%end%>

我的路线是：

resources :users do
     resources :tattoos
      resources :comments
end

表格有效，我可以提交，控制台显示：

  Parameters: {"utf8"=>"✓", "authenticity_token"=>"t6/o2soSU9fAKW/3Sro2kSbyc5WBrs/F0xMIKbwAKaU=", "comment"=>{"commentable_id"=>"4", "body"=>"sdfsdf"}, "commit"=>"Add comment", "user_id"=>"1", "tattoo_id"=>"4"

但是什么都没做，我做错了什么？

你没有打电话给

@comment.save

！天哪，我是个白痴。问题解决
